Help! Need advice

I live in LA and need to buy a used car. I love unique cars, horsepower, muscle cars and European sport cars. I need it to seat five, get decent gas milage, not be super expensive to repair, be a reliable and safe daily driver, and look cool and different. I want to spend under 20k. I'm lost, I'm a girl that likes guy cars, but I no longer have a hubby's to help me work on them. I spend time in traffic so id like an automatic, and something small enough to park in LA. I am a former goth now more Victorian chick that loves cars and driving fast. If I could I would get a new camaro or challenger, a hot rod 30s ford, suicide door lincoln, an old mini or Porsche 356 1956 speedster. How do I combine practicality and unique power on a budget? It's like the holy Grail! Ideas?
